This class provides methods for managing memory using CRT memory routines.
Syntax
class ATL::CCRTAllocator
Members
Public Methods
| Name | Description |
|---|---|
| CCRTAllocator::Allocate | (Static) Call this method to allocate memory. |
| CCRTAllocator::Free | (Static) Call this method to free memory. |
| CCRTAllocator::Reallocate | (Static) Call this method to reallocate memory. |
Remarks
This class is used by CHeapPtr to provide the CRT memory allocation routines. The counterpart class, CComAllocator, provides the same methods using COM routines.
Requirements
Header: atlcore.h
CCRTAllocator::Allocate
Call this static function to allocate memory.
static __declspec(allocator) void* Allocate(size_t nBytes) throw();
Parameters
nBytes
The number of bytes to allocate.
Return Value
Returns a void pointer to the allocated space, or NULL if there is insufficient memory available.
Remarks
Allocates memory. See malloc for more details.
CCRTAllocator::Free
Call this static function to free memory.
static void Free(void* p) throw();
Parameters
p
Pointer to the allocated memory.
Remarks
Frees the allocated memory. See free for more details.
CCRTAllocator::Reallocate
Call this static function to reallocate memory.
static __declspec(allocator) void* Reallocate(void* p, size_t nBytes) throw();
Parameters
p
Pointer to the allocated memory.
nBytes
The number of bytes to reallocate.
Return Value
Returns a void pointer to the allocated space, or NULL if there is insufficient memory.
Remarks
Resizes the amount of allocated memory. See realloc for more details.
